The motion conversion mechanism () includes a movable part (, which is arranged in parallel with the output shaft () and is configured to perform the linear motion. The movable part () and the motor () overlap one another in a radial direction of the motor (). A sensor target () is arranged in the moveable part, and a non-contact sensor () configured to detect a position of the sensor target () in a linear motion direction in a non-contact manner is arranged in the motor case ().
